抄録
A manuscript of the Enseiron (厭世論) was found in the Shinpukuji's (真福寺) manuscript collection. The text appears to be a Zen work composed in Japan during the Heian period by Seishi-Hosshi (斉志法師). The manuscript dates from the 5th year of the Enkyu (延久) Era (year 1073AD) of the Heian Period. The scripture belongs to the doctrinal literature of Zen Buddhism, and its author, Seishi-Hosshi, underlines the importance for ascetics to read and study Zen works (達磨蔵). Despite the fact that I carried out investigations on the author, his life and activities remain unknown. The discovery of this manuscript raises questions regarding the traditional view that Zen Buddhism was introduced to Japan by Zen Masters Nonin (能忍), Eisai (栄西), and Dogen during the Kamakura (鎌倉) period.
